Title: Current source circuit
Inventor: MIYAKE TOSHIHIDE
IPC: G05F3/26
Filed: 1991-05-23
Abstract: PURPOSE:To outputs a current whose value is proportional to the absolute temperature and larger than a temperature characteristic by connecting the emitter of a transistor(TR) to a power source terminal through a 2nd resistance and the other terminal of a 1st resistance to the power source terminal. CONSTITUTION:The base of a TR Q1 and one terminal of the 1st resistance R1 are connected to the output of an absolute temperature proportional current source 12 which outputs the current having a temperature characteristic proportional to the absolute temperature, and the emitter of the TR Q1 is connected to the power source terminal G through the 2nd resistance R2. Further, the other terminal of the 1st resistance R1 is connected directly to the power source terminal G. In this case, the absolute temperature proportional current source 12 consists of eight TRs Q11-Q18 and two resistances R11 and R12 and a current mirror 11 consists of a diode D2, a TR Q3, and a resistance R3. The emitter area of the TR Q11 is larger than the emitter area of a TR Q12. Therefore, the current having the large-value temperature characteristic is obtained.

IPC: B29C45/00
Filed: 1978-12-05
Abstract: PURPOSE:To provide a valve nozzle which is properly actuated by resin pressure and which enables preventing a resin from flowing backwardly, by forming a cylinder and a piston such that  the inner diameter of the cylinder and the outer diameter of the piston are greater at the rear end  portions thereof and smaller at the front end portions thereof, whereby the valve can be opened  in the direction in which the resin is injected. CONSTITUTION:A valve nozzle consists of a cylinder 11, which constitutes a valve nozzle body, a  piston 12 slidingly moved in the cylinder, a valve stem 13 and a valve 14. The inner diameter  of the cylinder 11 is greater at its rear end portion 15 and smaller at its front end portion 16.  The outer diameter of the piston 12 is greater at its rear end portion and smaller at its front  end portion. The piston 12 has a passage 19 through which a material is passed, and a spring  21 is provided between the piston and the smaller-diameter portion 16 of the cylinder. When  a material is injected into the cylinder to fill the latter with the former, the piston is forwardly pressed against the spring 21 by the pressure of the material and due to the difference between the  surface areas of the front and rear portions of the piston to allow a gate 20 to be opened. When  the injection has been finished, the injection pressure decreases so that the valve is closed by the  elastic force of the spring 21. The valve is properly closed by the pressure of material which  flows backwardly in the cavity. The gate may be increased in diameter.
